ROLLER BEARING.

UNITED STATES PATENT OFFICE.

PIERRE DANSEREAU, OF MONTREAL, CANADA.

ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 561,971, dated June 16, 1896.

Application filed February 17, 1896. Serial No. 579,624. (No model.)

To all whom t may concern:

Be it known that I, PIERRE DANSEREAU, a citizen of the Dominion of Canada, residing in the city and district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Roller-Bearings and I do hereby declare the following` to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention has reference to a roller-bearing'especially adaptable to carriage-axles, but that can be used for bearings on line-shafting, rbc.; and it consists in rollers inserted between the box onto which is placed the hub and a tempered bush placed directly over the journal of the axle, so that it is not subject to wear, and the tempered bushes and rollers are very easy and cheaply replaced. I provide rollers at both ends of the journal, this allowing the box surrounding it, and onto which is placed a wheel-hub of approved construction.

This invention relates to roller-bearings; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure lis a general outside elevation. Fig. 2 is a longitudinal section; Fig. 3 is a section on line X X of Fig. 2. Fig. l is a section on line Y Y of Fig. 2.

' Fig. 5 is an elevation of my rollers when kept in place by means of rings. Fig. 6 is a plan view of same.

A is an ordinary axle, over the journal B of which is placed the sleeve or box O, onto which is placed the hub of the wheel. (Not shown.) This sleeve or box C is enlarged at each end C and C2, so as to permit the insertion of my rollers, and its inside diameter in the intervening portion C3 is just enough to clear the journal Il, so that the latter does not touch it.

D is an ordinary collar on the axle A, provided with the leather washer d; also, the lost motion at its outer end E can be taken up in any suitable well-known way, while my roll ers consist in a series of rollers F, inserted in the portions C and C2 of the sleeve or box C over tempered bushes G, fitting loosely on the journal B of the axle A, so as to be easily inserted and extracted and perfectly free to turn as they please.

The rollers F are held in place by abutting against the shoulders formed by the enlargement of the sleeve or box C and by means of the washers II and small annular projection J, over which is placed the washer K. The washers'H and K can be made out of any suitable material, but preferably out of steel.

Instead of putting my rollers F in loosely I can secu re them in two rings P, Figs. 5 and 6.

To remove the rollers, all that is necessary to do is to take off the wheel, remove the washers IAI and K, and pull out the bushes G, when if the rollers F are loose they will fall out, while if they are secured by end bearings in the rings P they are removed bodily. Of course to insert new ones the bushes G are first inserted, and then the rollers, and if the arrangement is as shown on Fig. 2 the annular projection or shoulder J is cut away for a short distance, (not shown on the drawings,) so as to permit the passage of a roller, so that they are pushed in through this opening.

Having described my invention, what I claim, and desire to secure by Letters Patent, Is-

The combination, with an axle provided with a journal B having a collarD at one end, and a screw-threaded projection N at the other end; of a washer d of soft material next to the collar D; a sleeve encircling the journal and provided with cylindrical chambers at its ends, the outer chamber C' having an annular projection J bushes G j ournaled on the bearing in the said chambers, rollers F interposed between the said bushes and the inner faces of the chambers, a washer H arranged between the rollers and the washer d at the inner end of the journal, a washer K bearing against the projection J, and a nut engaging with the projection N and bearing against the washer K, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

PIERRE DANSEREAU.
